BRUSH-BBIIDLE.

Specification of Letters Patent.

Patented July 6, 1909.

Application filed April 21, 1906. Serial No. 313,001.

To all whom it may concern:

Be it known that I, BERNARD O. Gnvnonrr, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Brush-Bridles, of which the following is a specification.

This invention relates to brush bridles especially adapted for use on stencil brushes to stiffen the bristles thereof and to prevent them from bending unduly when the brush is in use and adjustable on the bristles as the same become worn, and the said invention consists in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings :-Figure 1 is a perspective of a brush provided with a bridle embodying my invention. Fig. 2 is a detached perspective view of the bridle. Fig. 3 is a perspective view of a bridle constituting a modified form of my invention. Fig. 4; is a similar view showing another modified form of the invention.

The bridle shown in Figs. 1 and 2 consists of two sheet metal members 10 oppositely bowed and arranged with their ends overlapping to form a band to extend around the bristles of the brush, the said members being provided each with a central arm 11 formed integrally therewith and extending vertically from the upper end thereof and provided with vertically spaced perforations 12 for the re ception. of fastening means such as tacks or pins 13 whereby said arms may be secured to the base of the brush. handle. The said band is rendered adjustable to brushes of any diameter and is enabled to maintain the attaching arms at diametrically opposite points. This is effected by providing the members of the band with tongues, one of the said members having a tongue 16 at one end. and the other having a tongue 16 at the opposite end, the said members being further provided respectively with loops 17 -17 for the rece tion of the tongues, the latter being slidab e in said loops and each bearing against one of the members as will be understood from an inspection of Fig. 2. The tongue 16 is disposed eXteriorly of the band and the tongue 17 is disposed interiorly thereof. To secure the members of the band in adjusted position, it is only necessary to bend and double back the end of the tongue 16 as shown in Fig. 1

shown in Fig. 8, the band 10 is open on one side and the said opening is closed bya section 19 provided with a longitudinal slot 20. Adjusting screws 21 engage the end portions of the band, operate in the said slot and may be tightened on the section 19 after the band has been properly adjusted. The band is shown as provided with an integral vertically disposed arm 11.. A similar arm is formed integrally with the section 19.

In the modification of the invention shown in Fig. 4:, the brush bridle comprises two oppositely bent strips 24 arranged to form a band, the ends of one strip overlapping those of the other, said. overlapping ends of the said strips being formed at their upper edges with inturned flanges 25 which slidably engage over the upper edge of the adjacent strip and cooperate with the fastening means for holding the strips of the band in alinement. Said fastening means consists of elongated slots 20 in the overlapped. ends of one of the members and screws 21. which operate in said slots and engage the ends of th e other member as shown for clamping the overlapping ends of the members slidably together. Each member or section of the band or strip is formed with an arm 11 which rises from its upper end, the said arms being integral therewith and provided with openings 1.2 and being disposed op )osite each other.

Having thus .escribed the invention what I claim as new is,

1. A brush bridle comprising two sheet metal members oppositely bowed and arranged with their ends overlapping to constitute a two-part band for encircling the bristles of a brush, central arms formed integral with the members and rising vertically from the upper edges thereof and provided with vertically-spaced perforations, and fastening means between the overlapping ends of the members for permitting the band to be expanded or contracted while main taining the said arms at true diametrically opposite points, each means including an opening in one member, and a device on the other member removably and adjustably engaging in the opening. l 2. A brush )ridle comprising two sheet metal members oppositely bowed. and arl ranged with their ends overlapping to con stitute a two-part band for encircling the bristles of a brush, fastening arms formed in tegral with the members and rising vertithe modified form of the invention cally from the upper edges thereof and provided With vertically-spaced perforations, and fastening means securing the overlapping ends of the members together and permitting the band to be expanded or contracted While maintaining the said arms at true diametrically opposite points, each means including an elongated opening in one member, and a clamping device on the other member extending through the opening for adj ustably connecting the members together.

3. A brush bridle comprising two oppo sitely-bent strips arranged to form a band, the ends of one strip overla ping those of the other, means for adjustab y connecting the overlapping ends of the strips together and a flange on one of the strips arranged to slidably engage over the edge of the adjacent strip to cooperate with the fastening means for holding the strips in alinement, said means each consisting of an elongated opening in the extremity of one strip and extend ing longitudinally thereof, and a screw secured to the overlapping member and passing through the slot for clamping the overlapping ends slidably together.

In testimony whereof, I afiix my signature in presence of two Witnesses.
